ROLLING SCREEN.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed February 26, 1917. Serial No. 151,016.

. To all whom it may concern:

Be it known that I, JULIEN A. BRIED, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented a new and useful Improvement in Rolling Screens, of whichthe following is a specification and a which is illustrated in theaccompanying drawings. Y Y I My inventlon relates to the improvement inrolling screens as applied towindows and other openings for the keepingout of flies and insects, and has for its objects the production of arolling screen of simple construction easy to install and which will beextraordinarily tightly stretched when in position over the windowopening and also effectuall sealed at the edgesagainst the entrance 0insects, without the necessity of running the edges of the screen in agroove.

I attain the objects outlined above by thev device illustrated in thedrawings accompanying this specification in which Figure 1 is aperspective view of a window casing as seen from the inside of a roomand shows a rolling screen of my improved construction in position withthe screen rolled up.

Fig. 2 is a-larger View of a vertical cross section of the device withthe screen pulled down to cover the opening.

Fig. 3 is a cross section taken through the line a, a of Fig. 1 andshows the screen fabric seated at its edges and overhanging archedstrips secured to the casing at both sides.

Fig. 4 is a similar view to Fig. 3 and shows a variation in the form ofthe arched seating strips permitting a greater overhang of the screenedges with a given width of fabric.

Fig. 5 is a view of the tension lever i'n locked ,position.

A clear understanding of the improvement embodied in my rolling screenwill be had upon a more detailed reference to the drawings as follows.In Fig. 1 the screen carrying roller. 2 is shown positioned at theinside upper part of a window (the sheet metal dust casing 16 and theregular window shade roller 15 and its brackets 18 all shown in Fig. 2being omitted to show more clearly the novel features of my invention.)The screen fabric 1 is attached by its upper edge to, and shown rolledup on, a spring actuated roller 2. This roller is secured in place onthe. window casing by the brackets 3, 3' and is a common spring shaderoller (preferably of the metal variety) with the exception that itdispenses with the usual pawl (to hold a shade at various heights) andhas a gear wheel 4 secured to one end.

The brackets 3, 3 are similar to the,ordi-' nary shade roller supportingbrackets adapted to rotatably support the roller and hold the rewindingspring at any desired tension. I

The screen fabric 1. which may be of light woven wire though I prefer apainted or water-proofed cotton cloth screenjabric on account of itsgreater flexibility, has a stick 5 attached to its lower end, withseveral metal eyelets depending therefrom adapted to engage with thesill plates 7 to securely hold-it when the screen is pulled down.

After pulling down the screen and securing it in place the toggletension lever 8 is pushed upward to force the short rack on the upperend of the rod 9 into engagement with the gear wheel 4 on the end of theroller to forcibly turn it and cause great tension in the fabric, Fig. 5showing the locked position of the tension lever 8 when pushed upward.

. On each side of the window casing is secured a strip 10, preferably ofwood, projecting a short distance from the surface of the window casingand against which strips the screen fabric rests when pulled down.

The strips 10 are sprung away from the surface of the window casing inthe center before securing them firmly in place so as to form convexlyarched seats; as clearly shown at 12 in Figs. 1 and 2; and againstwhichthe screen fabric tightly seats itself along both edges whenforcibly stretched .with the tension device as described.

The screen fabric would seat itself against the arched strips throughthe screen tension produced by the action of the spring roller alone,but the tension of the ordinary spring roller would not cause as snug aseat on the strips as the very great tension produced by the rack andpinion device shown. In fact with this or a similar tensioning devicethe roller need not be spring actuated at all in so far as this featureof my invention is concerned and the fabric could be rewound by anyother desired means.

To assist in making an insect tight joint along the edges when thescreen is pulled down, I also allOW the fabric to overhang the archedstrips as shown in Figs. 3 and 4 at 11, the greater overhang shown inFig. 4 bein due to the seating portion of the strips being placedfarther inward from the edge of the window casing.

The strips 10 instead of being sprung to an arched condition and nailedto the edge of the window casing, may if desired be formed to therequired curve and attached to the face of'the casing at the edge of thewindow opening, but the method described of springing the strips to thearched form is simpler.

At the upper edge of the window opening is secured another strip 13 inFigs. 1 and 2. This strip'projects sufliciently to allow for thethickness of fabric when rolled up on the roller and provides a seatagainst which a portion of the fabric bears across the width of thewindow opening at the top when the screen is pulled down and forms aninsect seal across the top of the window opening.

The lower ends of both arched strips are notched at 14 Figs. 1 'and2,one half the thickness of the stick 5 attached to the lower end of thescreen, to allow the fabric to come in contact with the strips justabove that point.

Fig. 2 is a vertical cross section of the screen when pulled down andshows the position of the screen roller in relationto the standard shaderoller, the latterbeing shown at 15 and it will be observed thatmyscreen fabric sheet- 1 pulls down between the regular shade roller 15and the windowcasing and is also narrow enough to come down between theend brackets 18 ordinarily used.

to support the shade roller. At .16 in the same figure is shown in crosssection a metal protective casing almost surrounding the roller screento protect it against dust when rolled up; the dust casing may besupported ,on the end brackets 8, 3', or on the window casing or both.At 17 is indicated the actuating or rewinding spring within the screenroller 2, but no importance attaches to any particular construction'of'this feature, for an common spring shade roller may be used.

t might be mentioned at this point that if desired my screen can easilybe adapted to cover but part of the window opening by arranging a stoppiece across the opening at the desired point and securing the stick 5at the lower endof the screen, to the stop piece instead of to thestill.

Having thus descrlbedmy'lnvention it will be seen that I have providedaroll-ing window screen of simple construction which is sealed at theedges by seating itself. tightly against arched stripsjattached. to thewindow casing and is easily applied to the inside of a window casingjust above and without interference with the. regular shade roller andalso, that while I have shown and described a te sioning devicewhichacts on the be used and Salli acting on the roller as shown in thedrawing 7 I feel entitled to cover in my claims any method of manuallyand forcibly tensioning a roller screen apart from a spring within theroller and also an arched or curved seat at the edges of an opening usedwith any kind of a screen whether on a roller or simply stretched overthe opening, and likewise these principles if applied to shades insteadof screens as I believe them to benewand useful in either connection.
